To all whom it may concern:

Be it known that I WILLIAM D.MYERs, a citizenof the U 'ted ates, residing at Waynoka, in the-county of Woods, Oklahoma. Territory, have invented certain new and useful Improvements in Journal-Box Bearings for Rotary Disks of Drills {and I do hereby declare the following, to bee full, clear, and exact description of. the invention, such as will enable othe'rs'skilled in the art to. which it appertainsto make and use the same, reference beingjhad to the accompanying draw ings, and'to the letters of reference marked thereon, which: form a part of. this specification. f This invention relates to bearings for journal-boires forrotary disks of drills, and more particularl'y'the invention provides means to prevent dustorother foreign matter from entering-the bearing'.-.

More especi 11y the invention provides means consisting of a main body portion,-

having la recess upon one side thereof in I which the end of thedraw-bar may be bolted or otherwise-g'secured, and on theopposite side of that havi n the recess is a cylindrical ,bearing'portion w 'ch is received by the ro- I tary ece' which'fis, riveted or I otherwise secure toa ciittingrotarydisk, and project ing from' said be'aring' portion is a screwthreaded s indle'whichj isadapted to receive a 'bearingjisk "and also'a suitablenut to seplilierelyhold saidjbearing-disk upon the spin- Furthermore, ,thef invention provides meanszconsis'ting "ofj ai'plate, substantially as shown-in r ofathe drawings, to securely holdjsaidg beai'ing di'skin place and at the 'same-timeto'felamp the cutting rotary disk betweensaid plate and the securin -ring by means-oi tsior any other suitab e fasten, -fing, means Themam-body portion is also provided mthasuimble hard-oil cup to pro,- ;vido.s ui 'ble lubricating. means for the hearl 'hs-i iv tion consists in various details of and; Qmbinations and ar- 1 arts, which will be hereinafter I o e jpanyin'g' drawings, which, with the lettersof reference" marked thereon, form a part of application, and in which drawingsl describe and;then'specifically defined 5o inthe appe'nded clairn.-= I My'mvent on is illustrated in the accom- Figure 1 is a side elevation of a portion of a drill, showing my improved bearing applied to the draw-barandthe outtin rotary disk and also applied to the press-w eels in the rear of the hoe. Fig. 2 is a sectional view on line 2 2 of Fig. 1. Fig. 3 is a perspective view of the main body portion of the bearing lookingv at the side from which the spin-' dle projects. Fig. 4 is a detail perspective view of the main body portion of the bear ing looking at the op osite side, and Fig. 5 is a view of several of t e arts shown in Fig. 2

in readiness to be assem led.-

,Reference now being had-to the details of the drawings by letter, A designates a suitable draw-bar of a drill, the end of which is adapted ,to be received by'a recessed portion B in one side of. the main body portion C and securely held in place by a screw-threaded spindle D, which projects from the face- 0ft e recessed portion B. Said "spindle D is adapted to receive a suitable nut E to securely hold said draw-bar in position. To provide further means of securing said drawar, a suitable nut and bolt E are provided, as shown. clearly in Fig. 1 of the drawings. Upon the upper cylindrical portion of the main body ortion is an. offsetC, which is ada ted to ave secured thereto a suitable har -oil cup C1, as shown clearly in Figs. 1 and 2 of the drawings.

F designates a suitable duct which affords communication between .the hard-oil cup and the longitudinal recess F in the. conical surface of the bearing portion F. This duct is for the purpose of allowing the oil .to find its way to the bearing for the pu ose of lubricating the same. Adapted to t over the bearing portion F is a rotary 1piece F, and to the-circumferential flange tary iece is secured the cuttin rotary disk G. "l his rotary disk is securely old in lace b means of rivets H as shown clear y in F 2 of the drawings. Projecting from the bearing portion- F, as. shownv at G, is a screw-threaded spindle G, which is for the purpose of recelving the bearing-disk H, which is clearly shown in Fig. 2 of the drawmgs. suitable nut G to securely hold'the rotary disk in position with relation to the rotary piece F". Ada ted to fit over and to cover the bearing-dis H and the nut G is a plate H having suitable circumferential recesses of said ro- Said spindle is adapted to receive a hard-oil cup through the duct F to the recess F to escape after it has done its work, a suitable recess or opening J in the flange ofthe main body portion of the bearing is provided, as shown clearly in Figs. 2 and 3 of the drawings.

The descri tion of the detailed construction of the a ove-set-forth invention will be readily understood by reference being had to the accompanying drawings.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A dust-proof bearing comprising a member C having a recess in one face thereof, and

iece F a lug projecting from the bottom'of said recess, a draw-bar seated in said recess and having an aperture adapted to receive said lug, a nut fitted on the threaded end of said lug, said member having a conical bearing surface projecting from its face opposite said recess, a rotar hub portion provided with a bore with inc ined wall mounted upon the conical-shaped bearing-surface of said member, a disk fitted to said rotary hub portion, a threaded lug Gr projecting from one end of said member, a shouldered disk fastened to said hub portion, a washer inter osed between said shouldered disk and hu ortion, and a nut fitted upon said threaded lug G and engaged by said shouldered disk, as set forth.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

WILLIAM D. MYERS.
